Story summary

Researchers at Case Western Reserve University identified molecules called pseudo leukotrienes that may drive asthma-related inflammation.
Unlike traditional leukotrienes produced by enzymes, pseudo leukotrienes form when free radicals react with lipids.
The National Institutes of Health funded study suggests current asthma therapies that block leukotrienes may not address the root inflammation.
Asthma patients showed four to five times higher levels of pseudo leukotrienes, indicating potential biomarkers for disease severity.
